Answer:
Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation. Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.
Answer: 7,000 ohms
Explanation:
From the equation of ohms law V= IR
V=21 volt
I = 3 MA = 3.0×10^-3 A
So by evaluating, we have.
V= IR
21= 3.0×10^-3 × R
Then R = 21/3.0×10^-3
R= 7,000 ohms//.
Answer:
4.4857 seconds
No
Explanation:
L = Length of the pendulum = 5 m
g = Acceleration due to gravity = 9.81 m/s²
Time period is given by
The optimum time interval in between the pushes is 4.4857 seconds
It can be seen that the mass of the child is not used in the formula and hence changing the mass would not result in a different time period.
The length of the pendulum and the acceleration of gravity of the planet determines the time period.
The new electrostatic force will be 384 units.
The electrostatic force of attraction between two charges (charge of object 1) and (charge of object 2) separated by a distance d is given by
is the permittivity of free space.
Initially, we have,
Now, if the charge of object 1 is multiplied by 1, the charge of object 2 is multiplied by 3, and the distance separating objects 1 and 2 is divided by 4, we have, .
The new electrostatic force will be,
units.
We have,
Hence,
Hence, the new electrostatic force will be 384 units.
